Digital inputs
When allocating Group 2 as inputs, the UMG96 RM-E
has three digital inputs to each of which you can
connect one signal transducer. When a signal is present,
the corresponding LED lights up green.
An input signal is detected on a digital input if a voltage
of at least 10V and maximum 28V is applied and
where a current of at least 1mA and maximum 6mA
flows at the same time. Wiring longer than 30m must
be screened.
Note the correct polarity of the supply voltage!
